Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.0
Operating System: Linux 2.6.30-020630-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I had copied a file over to a phone card and after clicking a few times on the eject button of the Device Notifier plasmoid, plasma crashed and restarted. The volume was not unmounted.
